Taxonomy plugin breaks 'copy document type' functionality

• Generate project using archetype 1.05.02
• Add taxonomy plugin 1.08.02
• Create document type
• Add taxonomy picker to document type
• Save/commit document type
• Now try to copy the document type
• The copy dialog will freeze, an exception will be thrown (check logs)

Looks like this is caused by the classifiable mixin not being copied?

• When refreshing the browser, the new copy of the type will be visible but it will not load (some wicket exceptions are thrown).

Not sure if this is a bug in CMS, Taxonomy Plugin, or both. It's fairly common for a plugin to add a mixin, so this should not break any functionality.
